Solution 1

Try this in your code...place you all the control inside the ContentTemplate which are invoking the event and register them into the triger

XML

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Button runat="server" ID="update_Button" Text="Generate Random Number" Width="187px"
OnClick="update_Button_Click" />
<pre></ContentTemplate>
</asp:UpdatePanel>
<Triggers>
        <asp:AsyncPostBackTrigger ControlID="update_Button" EventName="Click" />
      
    </Triggers>

my project looks like this screen page,i have two data list control on the right side like
'TOP EXPERTS IN 24 HRS' and 'TOP EXPERTS IN MONTH'. if i click any one below that,the whole form has reload.so,can i use separate update panel for each data list control . is this a good

I believe it is best to use multiple UpdatePanel if you can because of the size the POST that the UpdatePanel generates.When you want only a certain part to be postbacked if you want entire page to be postback then it is better to use single update panel.

Make sure that you make the updatemode="conditional" for all the updatepanel otherwise all the updatepanel will get refreshed

difference for conditional mode and always mode

Mode="conditional' causes the updatepanel to update when one of following things happen:

1) If a control within the updatepanel causes the actual postback

2) If a trigger on the updatepanel updates
Otherwise, it won't update and refresh. When it is set to always, however, it will always refresh
